what major do you recommend for a person interested in pediatric oncology?

I have wanted to be a pediatric oncologist since I was 11, I'm getting ready to go to college and I want to make sure I pick the best possible major. I want to go to University of Florida or Auburn University. Auburn offers a biomedical major and a high acceptance to medical schools. I haven't visited UF but my family has a long line of gators so I've been going there since before I can remember. They don't offer a biomedical science major but they do offer a microbiology and cell science major that looks interesting. I don't know what their rate into medical school is but I am pretty sure it's high. I don't know which one to choose (based of majors ofc). Please help!!
